Understand The Working Principle Of Community Intercom Access Control
Community intercom access control is also called video doorbell system, scientific name is community intercom system, corresponding to non-visual intercom doorbell, which is a device for building calls. The visual intercom doorbell refers to the doorbell system of your home. We often say several words such as building intercom, video doorbell, and intercom doorbell. They all have the same meaning and refer to the intercom management system between the visitor and the host! Strictly speaking, the community intercom is a visitor management system, including software and hardware as well as after-sales service personnel.
Visual intercom is an audio-visual communication system for residents in residential communities and visitors, and an effective way for residents in residential communities to prevent outsiders from entering privately. Through the setting of the system, residents can use the intercom main unit/intercom extension at home, through the main unit of the intercom/visual intercom entrance set at the entrance of the unit building. When talking with the visitor, the visitor can be identified by the image on the extension screen. After the visitor confirms, the resident owner uses the door lock control key on the extension to open the electronic control door lock on the main unit at the entrance of the unit building to allow the visitor to enter. Otherwise, all personnel and strange visitors who are not in the building of this unit will not be allowed to enter.
Mainly used in commercial residential buildings, the scale is developing rapidly, and it has generally entered the urban high-rise residential area. When in use, the residents hear the ringtone, use the video phone, visitors call through the host downstairs door, and the residents can receive video images through the host camera downstairs. Residents observe the monitoring picture on the extension screen to confirm the identity of the visitor, and finally decide whether to press the unlock button of the indoor extension to open the electronic control door lock connected to the entrance host, allowing the visitor to open the door and enter.
The video intercom system can also be connected to alarm devices such as emergency alarm buttons, infrared detectors, magnetic door magnets, smoke detectors, combustible detectors, etc., to immediately notify and manage information such as illegal intrusion, fire alarm, gas leak, and emergency help. The center provides residents with a convenient and safe life, reduces the troubles of residents being disturbed, and is also a manifestation of the level of residential area and resident status.
